  • Composition for corrosion protection using metal silicides or alloys of silicon and metals
    Patent number: 4474606
    Abstract: A coating composition is provided which is suitable for the protection of corrodible metallic surfaces. The coating composition includes a binder and a filler, with the filler present in an amount sufficient to impart corrosion-resistant characteristics to the coating composition. The filler comprises conductive metal particles and particles of a metal composition which comprises silicon and at least one active metal. The metal composition can be an alloy of silicon with an active metal which is unstable when introduced alone into water or a silicide of an active metal which is unstable when introduced alone into water.
    Type: Grant
    Filed: April 21, 1982
    Date of Patent: October 2, 1984
    Assignee: Occidental Chemical Corporation
    Inventors: James P. McKaveney, Vernon P. Simpson
